a scroll-form at any required distance from the opposite half of the spring. This arrangement allows the spring to operate in its usual manner when an undue weight is not placed upon it, but when any sudden strain is thrown .upon, or it is overloaded in any manner, the spring, in its descent, meeting with the curved ends of the additional leaves B, is supported and sus- To all whom it may concern Be it known that I, CARE SHELDON, of Middleburg, in the county ofSehoharie, and State of New York, have invented a new and useful Improvement in Springs for Wagons, Carriages, 850.; and I hereby declare the following to be a full and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification.

This invention relates to that class of elliptic wagon-springs in which additional leaves are introduced for the purpose of breaking the descent of the upper elliptical portion, whenthe springs are-heavily loaded, and consists in attaching to the said upper elliptical portion, and to the scroll ends of the addition a1 leaves, rubber or leather bufi'ers, for the purpose oi' preventing the shock resulting from the concussion of the springs, when brought suddenly together, and also preventing the disagreeable noise attending such COHCUSSlOIl.

The following description will enable others skilled in the art to make and use my invention.

To any of the common and well-known forms of elliptic or half-elliptic springs A,the additional leaves B are secured, either by the clip 0, or by bolts, to the bed-piece D. These additional leaves are only secured to one part of the spring, either the lower By this means the danger of breaking the spring is materially" lessened. The springs for ordinary use maybe made much lighter than they are now, and all the requirements of springs for light and heavy work are combined in one arrangement. Should it be found necessary to deaden the noise caused by the striking of the spring upon the additional leaves, a thickness of leather or India rubber can be placed between them for this purpose.

Among the advantages of this spring are its simplicity, reliability, and cheapness.
